"Investing" is stock market is a gamble: the easiest way to learn that it is casino is by experience (invest and learn).
The problem is that the new generation will not listen suggestions of people which already learn things the hard-way - so there will be always fresh influx of suckers which think these 'old' people don't get it.
However, this does not mean that investment in stock market is a bad idea - but you need to consider it as 'poker': money management is very very important, learn to cut loses fast, you need to hedge (especially for unforeseeable events while market is closed), don't bet blind, etc.
